This screen shows the VPN passthrough, firewall, and filter settings. Use these features to enhance the security of your network.

VPN Passthrough

Virtual Private Networking (VPN) is a security measure that basically creates a secure connection between two remote locations. Configure these settings so the Gateway will permit VPN tunnels to pass through.

IPSec Passthrough. Internet Protocol Security (IPSec) is a suite of protocols used to implement secure exchange of packets at the IP layer. To allow IPSec Passthrough, click the Enable button. To disable IPSec Passthrough, click the Disable button.

PPPoE Passthrough. PPPoE Passthrough allows your PC(s) to use the PPPoE client software provided by your ISP. Some ISPs may request that you use this feature on the Gateway. To allow PPPoE Passthrough, click the Enable button. To disable PPPoE Passthrough, click the Disable button.

PPTP Passthrough. Point-to-Point Tunneling Protocol Passthrough is the method used to enable VPN sessions to a Windows NT 4.0 or 2000 server. To allow PPTP Passthrough, click the Enable button. To disable PPTP Passthrough, click the Disable button.

L2TP Passthrough. Layering 2 Tunneling Protocol Passthrough is an extension of the Point-to-Point Tunneling Protocol (PPTP) used to enable the operation of a VPN over the Internet.To allow L2TP Passthrough, click the Enable button. To disable L2TP Passthrough, click the Disable button.

Firewall

You can enable or disable the firewall, select filters to block specific Internet data types, and block anonymous Internet requests.

To use the firewall, click Enable. If you do not want to use the firewall, click Disable.

Additional Filters
